Local
When Local is set to Off, notes will only be played by the riff. When Local is set to On,
notes in the current zone can be played normally by the keyboard, and by the riff.
Loop
When Loop is set to Off, the riff will play once until it is retriggered. When Loop is set to
On, the riff will play in a loop until a key in the Release Range is released.
Riff Tempo
Use the Riff Tempo parameter to set the tempo of your riff. With Riff Tempo set to Song,
the riffs original tempo from song mode will be used. With Riff Tempo set to Multi, the
tempo set on the Multi Edit Common page will be used. The Multi setting is useful for
tempo syncing different riffs or arpeggiators. With Riff Tempo set to External, the riff will
sync to external MIDI clock. You can also manually choose a tempo by selecting a value from
20 to 400.
Trigger Master
The Trigger Master parameter determines which zone a riff will sync to when triggered. This
allows you to trigger riffs in sync with other riffs or arpeggios by syncing to the beat of riffs or
arpeggios in other zones.
For example, if you have a drum riff in zone 1 and a bass riff in zone 2, you may always want
the bass riff in zone 2 to sync to the drum riff in zone 1. In this case you would set the bass
riff Trigger Master to Riff Zone 1.
You may want to have a little more freedom and not be tied to the drum riff as the main
"timekeeper." Maybe you want to start with the bass riff and have the drum riff start later. In
this case you would set Trigger Master to First Riff. With this setting, the riff will look for
the first available riff to sync to. So if both the drum riff and the bass riff have this parameter
set to First Riff, the riff that is started first will be the master. If the bass riff starts first, the
drum riff will see that as the first available riff to sync to and will do so. If the drum riff is
started first, the bass riff will see that as the first available riff to sync to and will do so. This
can be very handy if you have multiple riffs and want to do some live remixing; you could
have the drums drop out, and—as long is there is a riff playing—they will sync back up
when triggered again.
You can also choose First Arp, which behaves the same way as First Riff, but makes your riff
look for the first available arpeggiator to sync to. A setting of First Riff/Arp will sync the riff
to the first available riff or arpeggiator.
Note: If you have multiple riffs or arpeggiators already playing when using First Riff, First
Arp, or First Riff/Arp for the current riff, the current riff will sync to the riff or arpeggiator of
the lowest numbered zone that has a riff or arpeggiator playing.
